Life on Earth - Biological Concepts from the Non-Science Major Perspective

Pine trees have a different way of getting through the winter. They have tough needles instead of leaves, and these needles can take freezing temperatures without being damaged. One trick they use is that the needles are covered with a layer of wax. This helps prevent freezing and water loss. They also contain natural anti-freeze chemicals that prevent them from freezing. The plants are able to continue photosynthesis just as long as they can get adequate water.

Based on a plants adaptations to environmental conditions there are a variety of paths that can be followed in the carbon fixation component of photosynthesis.

Plants have stomata in their leaves which can open and close based on environmental conditions. However, when stomata are closed, carbon dioxide cannot be collected.

The question: Are there any other adaptations that plants have made to adjust to environmental conditions?

There are numerous interesting physiological "adaptations" that plants have that make them able to uniquely survive in their varied environments.

You mentioned pine needles that stay on trees. Well, consider deciduous trees that have leaves that fall from the trees during the winter. Generally, these are broad leaves with huge surface areas. They are ...
